This invention relates to gauges andmore particularly to gauges for gauging. the

r I length of the bearing portions of wiredraw:

ing dies, and has for its object the'provi- 5 sion of a gauge bywhich the length of the bearing portions of wire drawing dies may be accurately andiquickly 'gauged.

The bearing of a wire drawing die is that" slightly tapered portion of the hole which has the least diameter and which gives the W'ire'its required size. Nire drawingv dies whether'ma de of cast iron or forged steel, must have the proper length of bearing,

- since the length of the bearing determines '15 the length of servlce of the hole, that is,

a hole with a standard length of bearing will permit more bundles of wire to be drawn through it than one with a shorter constructed in accordance with this invention and showing a template in position for setting'the gauge. a

Figure 2 is a similar view showing a die in ositionto be gauged.

igures 3 and 4 are elevations of the different pointers or gauge tools for use with the gauge.

Referring more particularly to the drawings, the numeral 2 designates the base of the gauge apparatus, which is provided with a split socket 8 at one side adapted to re- I ceive an upright rod or post 4. The socket 3 is provided with a clamping screw 5 for clamping the socket around the post 4.

An indicator support or'bracket 6 having a tubular portion 7 is slidably mounted on the post 4 and its downward movement is limited by a split collar 8 which is adjustable on the post 4 and adapted to'be locked in position by a thumb-screw 9,

An indicator 10 of any standard design and construction which has a plunger 11 adapted to move a hand 12 in either directionfrom zero in response to a vertical movement of the plunger is mounted on the support or bracket 6.

The lower end of the plunger ll is threadpreviously formed accurately therein, such of my claims.

ed as at 14, and tapered or cone-'shaped'fgauge too-lsor points '15 provided with threaded recesses orfsockets 16 are remov I ably threaded thereon and. are adapted to fit-within thefdieholes in the drawing dies,

The tools' or points 15 may have-varying tapers and" consequently; be' of varying lengths as shown in Figures 3 and 4. a In operation, a template 18 having the, proper length and diameter of bearing-for the die to be gauged is placed on the base 2.

The correct type of tool or point 15-is then I selected and mounted on the plunger 11. '1 The bracket 6 is then adjusted vertically on the post 4 so that when the tool or point 15 is engaged with the bearing of the template 18, the indicator 10 will readzero. -The bracket 6 is then p evented from moving downwardly by locking the'collar 8 inposi-v tion below the bracket 6. 1 ,i The template 18 is then removed. and a die plate 19 having die holes 20 is substituted therefor. The die plates 19,-it will be understood, have the 7 bearing portions 21 bearing portions being accurately reamed to exact finish diameter prior to the reaming out and finishing of the cone shaped upper or entering side of the die holes 20. The tool or point 15 is then inserted in each or the holes 20 so that each may be gauged;

'Since the bearing portions 21 are all of the same and correct diameter, any variations in the length of the bearing portion 21 01": the die holes 20 will register either plus or minus on the dial of the indicator 10, since the plunger 11 will move downwardly beyond its zero setting it the bearing is short, or will not move down to its zero settingif the bearing is long. ,7 1
